The RS-UV3 is a shot in the arm for amateur radio. The RS-UV3 lets you build your own Arduino- or Raspberry Pi–based radio. The US $90 RS-UV3 radio shield from HobbyPCB is an FM transceiver that’s welcoming by design and built for makers from the ground up. It’s not the only radio shield available for →

New research suggests that software piracy has a detrimental effect on the adoption of Linux desktop operating systems. Piracy is one of the reasons why Windows has been able to maintain its dominant market position, making open source alternatives “forgotten victims” of copyright infringement. https://torrentfreak.com/software-piracy-hurts-linux-adoption-research-finds-160221/ Posted from WordPress for Android →

Dr. Paul Kelley, a researcher at Oxford University, has scientifically corroborated the claim that nearly every worker to ever live has made: that it sucks to work before 10 AM. “Before the age of 55, the circadian rhythms of adults are completely out of sync with normal nine-to-five working hours, posing a “serious threat” to →

We have all heard about or seen on TV Alexander Stubb welcoming the last OECD report about Finland, and congratulating himself and the government on the support for OECDs to the Finnish government’s program. That is just a communication trick. because this optimistic is simply wrong http://finlandpolitics.org/2016/02/17/what-the-oecd-has-really-said-about-finlands-economy/ Posted from WordPress for Android →

What is impedance? Impedance is very technical measurement that is hard to explain without equations and some scientific jargon. When you want to understand impedance, first think about electrical resistance (represented by R), measured in Ohms. In basic battery circuit battery generates a voltage which tries to force a current around the circuit connected between →

There is a wide variety of sensor0s. A sensor can be used to measure all manner of different things including temperature, light, vibrations… heck even air quality and your heartbeat! By connecting a sensor to Arduino board you can easily read sensor values and have your own code to process them. If you connect your →

Cameras and audio equipment are getting better all the time, but mostly through brute force: more pixels, more sensors, and better post-processing. Mammalian eyes and ears beat them handily when it comes to efficiency and the ability to only focus on what’s interesting or important. Neuromorphic engineers, who try to mimic the strengths of biological →
